CLOSURE FOR RECEPTACLES.

Application filed June 25,

To all whom it may come m:

Be it known that l, SAMUEL BABrrzKY, a citizen of the United States,residing at Chicago, in the county of Cool: and State of Illinois, haveinvented new and useful Improvements in Closures for Receptacles, ofwhich the following is a specification.

The invention relates to improvements in closures for receptacles.

Receptacles are frequently closed by means oi a plug or cap seated in oron a tubular projection on the receptacle, the pro jcction having a pipethread. and the cap or plug also being provided with internal externalpipe thread respectively, for attachment to the device. These tine pipethreads are easily mutilated so as to render it difiicult to place theclosure in position. andeven where the threads are in good order theoperation of placing the cap in closing position is made di'tlicultsince the two threaded portions not usually enter into the necessaryholding engagement readily.

In the present application an unthreaded cap or cover is adapted to beplaced on the receptacle and is secured in position by a holding devicewhich in itself is automatically pressed into locking engagement whenthe cover is f reed on its seat. while it is released from its lock withthe release of i the cover from the seat.

It is an object of the invention to provide a closure for the receptaclewith a device for securely holding it in place. and to pro vide meanswherebyv the closure can be removed from the opening to be covered thereby only after release of a holding device.

Another object ot the invention is to provide a holding device 0t thischaracter which can be moved to releasing position only after theclosure has been partly elevated to opening position.

lt is also an object of the invention to provide a device'of thischaracter which is readily adaptable to receptacles of various forms andwhich can readily be attached and removed whenever desired.

With these and other objects in view, embodiments of the invention aredescribed in the following specification and are illustrated in theaccompanying drawing, wherem,

Fig. l is a perspective. fragmentary view of a portion of a receptaclewith the im proved cover shown in closed position;

Serial No. 722,321

2 is the top plan view of the same;

Fig. 3 is a vertical, sectional, central view taken through the coverand holding device;

Fig. 4 is a horizontal, sectional view on line ld of Fig. 3, and

Fig. 5 is a side elevation of the closure a--d holding device applied toa different receptacle.

The tank 1, shown in Figs. 1, 2, and 3, may be an ordinary gasoline tankhaving a tubular extension 2 to which by welding or in any othersuitable way a member is secured. This member is shown to be providedwith an annular flange etin engagement with the tubular extension 2 andhas an annular counter bore 5 in which the cover 6 may be firmly seatedso as to prevent discharge of the fluid from the tank. The cover 6 shownin Fig. 3 to be provided w'th a horizontal closing surface and cy dricalvertical surface adapted to seat against the horizontal and cylindricalportion respectively of the counter bore in the member 3.

This cover is maintained on its seat by a holding device which ismovably connected with the projection 13 of the in mber as for instanceby a shoulder screw 7 in threaded engagement with said projection 13 andpasses rotatably through a bore in the extension 8 of the bail shapedpart 9 of the holding device. The central portion of the bail shapedpartis enlarged to term a boss 10 having a tapped opening throughwl'iich thumb screw 12 extends. the lower part of the screw 12 beingwithout threads and rotatably seated in the central boss ll. t thecover. This cylindrical extension is provided with an annular groove 15through which a pin 16 secured in the boss l t pa... s. whereby rotationof this screw in the boss is rendered possible while axial movement ofthe screw relatively to the cover is prevented.

Opposite the extension 13 ot the member 3, the latter has anotherholdinghis; having an upward projecting part 17. and an inward directedhorizontal portion 18 adapted to enter into engagement with an extension19 on the bail shaped member 9.

The method of using this closure will be understood from the abovedisclosure. When it is desired to open the receptacle the cover 6 israised above the top plane of the member 3. as shown in dotted lines inFig. 3. The relative movement of the cover with respect to the holdingdevice 9 is effected by manipulation of the thumb screw 12. The coverstructure comprising the holding device 9 and the cover 6 itself maythen be swung bacl: about the pivot 7 so that the cover will free theopening in the receptacle, as shown in dotted lines in Fig. 2. Thereceptacle may then be filled, and the cover structure may then bereturned to do ted line position of Fig. 3. The thumb screw 12 ismanipulated again to lower the cover 6 on its seat, as shown in fulllines. lE hcn the cover is fully seated and the screw 12 is rotated, theholding device 9 with its extension 19 will be forced upwad against thelower face of the horizontal part 18 so as to trictionally secure thebail. shaped portion. in place against any accidental displacement. a

This safety against accidental displacement or even against intended butunauthorized opening of the closure may be enhanced. by providing thehorizontallup l8 wit: a bore 20 extending horizontally through the samewhich is in alinement with a similar bore 21 in the horizontal e tension19 ot the holding device 9 after the latter has been moved to operativeposition. A pin 22 may be driven through these two alined bores 20, 21,whereby a pivotal movement of the holding device about its pivotal pointmay be prevented, or where it is desired to prevent unauthorized accessto the receptacle, the bail of a padlock or similar device not shown maybe inserted through the alined bores so that even upon manipulation o1the holding screw 12 a release of the bail shaped member cannot takeplace. and therefore a removal of the cover 6 cannot be effected;

In the embodiment illustrated in Fig. 5 an oil can 30 is shown to beprovided with a removable cover 31 ha ing a discharge spout this coverhaving a diameter approxi mately equal to the upper diameter of the can.A member 3 with an extension 13 is secured to the upper margin of thecan for receiving the holding bail 9. The construction of the partsmaybe similar to those described in connection with the firstembodiment. In this embodiment the improved closure also will securelyprotect the contents of the can but will permit the can to be filledreadily without necessitating the removal of a threaded cap or plug, aninconvenience to closing position after filling ot the receptacle.

I claim:

1. A receptacle closure comprising a cover adapted to be seated over theopening of a receptacle, the receptacle being provided with a flangeseated in said opening and having a counter bore, the flange being alsopro *idcd with two diametrically opposite exteisions, a holding devicepivotally secured to one of said extensions and adjustably supportingsaid cover, and means interpose between said cover and said holdingdevice for forcing said cover into the counter bore and for "forcing theholding device into locking? engagement with the second extension. I

it receptacle closure comprising a cover adapted to be seated over theopening of a receptacle, a member inserted in said openi and havii acounter bore, the contour which corresponds to the contour of the cover,said member being provided with an extension, holding device connectedwith the cover and provided with a projection, said member havinganother extension with which said projection is adapted to engage, theconnecting means between the cover and holding device being formed by ascrew in threaded engagement with the holding device and rotatablysecured and held against axial displacement relatively to the cover.

A receptacle closure comprisinga cover adapted to be seated over theopening of a receptacle, a member fixed to the receptacle andsurrounding said opening, said member being provided with diametricallyopposite extensions, a holding device pivoted to one of said extensionsand having a projection adapted to engage the other extension, means insaid holding device for forcing the cover to closing position, and meansfor N reventing relative movement between said projection on the holdingdevice and the second extension on the member.

4-. A receptacle closure comprising a cover adapted to be seated overthe opening; of a receptacle, a holding; device pivoted to thereceptacle, a lug projecting from the receptacle and adapted forengagement with said holding; device, and a screw in threaded engagementwith the holding device and rotatably extending into the cover, wherebyupon manipulation of said screw in a pre determined direction the coverwill be forced over the opening and the holding de vice will be forcedinto locking engagement with the extension on the receptacle.

In testimony whereof I ailix my signature in the presence of twowitnesses at 10 South La Salle St, Chicago, Illinois.
